Augmented Reality in a Contact Lens

Posted by in categories: augmented reality, biotech/medical, computing, mobile phones

Science fiction writers envisioned the technology decades ago, and startups have been working on developing an actual product for at least 10 years.

Today, Mojo Vision announced that it has done just that—put 14K pixels-per-inch microdisplays, wireless radios, image sensors, and motion sensors into contact lenses that fit comfortably in the eyes. The first generation of Mojo Lenses are being powered wirelessly, though future generations will have batteries on board. A small external pack, besides providing power, handles sensor data and sends information to the display. The company is calling the technology Invisible Computing, and company representatives say it will get people’s eyes off their phones and back onto the world around them.

The first application, says Steve Sinclair, senior vice president of product and marketing, will likely be for people with low vision—providing real-time edge detection and dropping crisp lines around objects. In a demonstration last week at CES 2020, I used a working prototype (albeit by squinting through the lens rather than putting it into my eyes), and the device highlighted shapes in bright green as I looked around a dimly lit room.

Exosome Therapy for Stroke Produces Full Recovery in Animal Model

Posted by in categories: biotech/medical, neuroscience

Researchers reverse stroke damage in animal model using stem cell exosomes.


Expanding upon previous work that developed a treatment using a type of extracellular vesicles known as exosomes—small fluid-filled structures that are created by stem cells—investigators at the University of Georgia (UGA) present brain-imaging data for a new stroke treatment that supported full recovery in swine, modeled with the same pattern of neurodegeneration as seen in humans with severe stroke. Findings from this new study were published recently in Translational Stroke Research through an article titled “Neural Stem Cell Extracellular Vesicles Disrupt Midline Shift Predictive Outcomes in Porcine Ischemic Stroke Model.”

Amazingly, it’s been almost a quarter-century since the first drug was approved for stroke. Yet, what’s even more striking is that only a single drug remains approved today, so having a greater understanding of the molecular mechanisms that underlie stroke cases should lead to new therapies that could provide dramatic improvements in patient outcomes.

AI-Designed ‘Living Robots’ Crawl, Heal Themselves

Posted by in categories: biotech/medical, robotics/AI, supercomputing

Biological organisms have certain useful attributes that synthetic robots do not, such as the abilities to heal, adapt to new situations, and reproduce. Yet molding biological tissues into robots or tools has been exceptionally difficult to do: Experimental techniques, such as altering a genome to make a microbe perform a specific task, are hard to control and not scalable.

Now, a team of scientists at the University of Vermont and Tufts University in Massachusetts has used a supercomputer to design novel lifeforms with specific functions, then built those organisms out of frog cells.

The mysterious, legendary giant squid’s genome is revealed

Posted by in categories: biotech/medical, education

How did the monstrous giant squid—reaching school-bus size, with eyes as big as dinner plates and tentacles that can snatch prey 10 yards away—get so scarily big?

Today, important clues about the anatomy and evolution of the mysterious (Architeuthis dux) are revealed through publication of its full by a University of Copenhagen-led team that includes scientist Caroline Albertin of the Marine Biological Laboratory (MBL), Woods Hole.

Giant are rarely sighted and have never been caught and kept alive, meaning their biology (even how they reproduce) is still largely a mystery. The genome sequence can provide important insight.

The History of the Pharma Cartel

Posted by in categories: biotech/medical, business, health

The Supreme Court of the U.S. finds John Rockefeller and his Trust guilty of corruption, illegal business practices and racketeering. As a result of this decision, the entire Rockefeller Standard Oil-Trust, the world’s largest corporation of its time, was sentenced to be dismantled. But Rockefeller was already above the Supreme Court and did not care about this decision.

In order to disperse public and political pressure on him and other robber-barons, Rockefeller uses a trick called “philanthropy”, whereby the illegal gains from his robber-practices in the oil business are used to launch the Rockefeller Foundation. This tax haven was used to strategically take over the health care sector in the U.S…

The Rockefeller Foundation was the front organization for a new global business venture of Rockefeller and his accomplices. This new venture was called the pharmaceutical investment business. Donations from the Rockefeller Foundation went only to medical schools and hospitals. These institutions had become missionaries of a new breed of companies: the manufacturers of patented, synthetic drugs.

Coronavirus Vaccine

Posted by in category: biotech/medical

The current threat of avian influenza to the human population, the potential for the reemergence of severe acute respiratory syndrome (SARS)-associated coronavirus, and the identification of multiple novel respiratory viruses underline the necessity for the development of therapeutic and preventive strategies to combat viral infection. Vaccine development is a key component in the prevention of widespread viral infection and in the reduction of morbidity and mortality associated with many viral infections. In this part, coronavirus vaccine, especially SARS-CoV vaccines are mainly discussed.

Coronavirus vaccines can be inactivated coronavirus, live attenuated coronavirus, or S protein-based. Besides, there are still vectored vaccines, DNA vaccines, and combination vaccines against coronaviruses. Vaccines targeting several animal CoVs have been developed, and some have been demonstrated to be efficacious in preventing viral infection. However, a phenomenon of enhanced disease following vaccination has been observed in cats upon infection with feline infectious peritonitis virus following previous infection, vaccination, or passive transfer of antibody. The phenomenon is not fully understood but is believed to be a result of enhanced uptake and spread of the virus through binding of virus-antibody immune complexes to Fc receptors on the surfaces of macrophages; low-titer (subneutralizing) antibodies directed against the S protein are mainly responsible. Although antibody enhancement appears to be limited to feline infectious peritonitis virus among CoVs, similar concerns have been raised with regard to SARS-CoV. Previously infected mice and hamsters are protected from subsequent infection with SARS-CoV in the absence of enhanced disease, and vaccine studies and passive immunoprophylaxis performed with mice and hamsters suggest that previous exposure and the presence of NAbs provide protection.
